N=2 SUPERCONFORMAL MINIMAL MODELS
No full textFusion rules, structure constants and 4-point functions for all the fields in the Neveu-Schwarz, Ramond and twisted sectors of N = 2 minimal models are presented. It is shown that the additional Zp+2 symmetries of these models are generated by specific chiral N = 2 superfields. The structure of the corresponding N = 2 superparafermionic models is discussed
FUSION RULES, 4-POINT FUNCTIONS AND DISCRETE SYMMETRIES OF N=2 SUPERCONFORMAL MODELS
No full textFusion rules, structure constants and four-point functions for all the fields of N = 2 superconformal minimal models (c ≤ 3) are derived. It is shown that the additional Zp+2 symmetries of these models are generated by specific N = 2 superfields which close the N = 2 superparafermionic algebra. General results are applied to the four- and three-generation Gepner tensor product models and the allowed Yukawa couplings are found. © 1989

Integrable perturbations of CFT with complex parameter: The M3/5 model and its generalizations
No full textBy using the thermodynamic Bethe ansatz approach, we give evidence of the existence of both massive and massless behaviors for the φ2,1 perturbation of the M3,5 nonunitary minimal model, thus resolving apparent contradictions in the previous literature. The two behaviors correspond to changing the perturbing bare coupling constant from real values to imaginary ones. Generalizations of this picture to the whole class of nonunitary minimal models Mp,2p±1, perturbed by their least relevant operator, lead to a cascade of flows similar to that of unitary minima] models perturbed by φ1,3. Various aspects and generalizations of this phenomenon and the links with the Izergin-Korepin model are discussed
RAMOND SECTOR OF THE SUPERSYMMETRIC MINIMAL MODELS
No full textA Coulomb gas representation for the Ramond sectors of the N = 1 supersymmetric models is constructed. The fusion rules and the 4-point functions for the Ramond fields are calculated explicitly by this method and used to describe the Z2 odd sectors of the tricritical Ising model and of the critical Kosterlitz-Thouless XY model
